GUARD.

SPECIFICATION forming part of Letters Patent No. 325,666, dated September l. 1885.

Application tiled July 1l, 1684. (No model.)

.To all 1071/0111, it may concern;

Be it known that I, LnsLin T. HARDY, a citizen of the United States, residing at Houston Mines, in the count-y of Botetourt and 5 State of Virginia, have invented certain new and useful Improvements in Cattle-Guards, of which the following is a description.

Figure 'l is a plan of the cattle guard applied to arailroad-track. Fig. 2 is a side view 1o ofthe same, with two of the cylinders broken open or in section.

The object of my invention is to provide a cattle-guard for railroad-tracks which will prevent cattle from passing from one field into 1 5 another or Vfrom a iield into a road at the point where the continuity of the fence is broken by a railroad-track.

My invention relates to that form oi' cattlegnard in which a series of rollers are arranged 2O in bearingsin the track-bed, and in revolving, from contact with thehoof ofthe animal, deters the latter from passing over.

My invention consists in constructing these rollers in the shape of hollow cylinders, and

5 placing within the same resonant fragments of metal or other material, which, when agitated by the motion of the cylinder, i'rightens animals back.

It also consists in constructing said cylinders with longiludi nal ilutes, which canse them to be more positively revolved by the animal, and also serve to increase the agitation and noise et' its contents.

, It also further consists in gearing all the 5 cylinders together for cumulative effect, and still further in providing intermediate cones with revolving or stationary balls for preventing the animal from finding a foothold be tween the cylinders, as hereinafter fully de- 40 scribed.

In the drawings, A A represent the railroad track-rails. BB are sills arranged outside the track-rails and parallel with them. O are the revolving cylinders, which are made of any suitable material, and are formed with longitudinal flutes in their peripheries, which are concave upon the outside and convex upon the inside, forming a sort ol' hexagonal cylinder. These cylinders are jonrnaled in bearings E,

in the sills B, and are coupled together by 5o chain-wheels H and chains I, so that they may all revolve together. D are plates placed between the cylinders and parallel with and just above the crossties, which plates are provided with numerous cone-like projections, a, which have knobs or balls D at their upper ends, which, by preference, are made to revolve.

lVithin each cylinder is placed a quant-ity of resonant material, c, such as metal scraps, broken glass, &c., which, when the cylinders 6o are turned by the foot of the animal, produces a noise or racket that alarms the animal and causes it to back out.

In defining my invention with greater clearness, I would state that I am aware that revolving rollers have been heretofore employed in a railroad -track bed, and I do not claim th ese broadly.

In modifying my invention I may prefer to use selfgearing cylinders, or cylinders whose longitudinal wings or lint-es gear into each other. I may also use cylinders and plates in other relation than that mentioned.

Having thus described my invent-ion, what I claim as new is* 1. A cattle-guard for railway-tracks, consisting of a series of revolving cylinders or chambers having within the same resonant material, which is set in agitation by the movement of the cylinder, as described.

Z. A cattle-guard for railway-tracks, consisting of a series of revolving cylinders or r llers, combined with chain wheels and a chain for gearing them to revolve together.

3. A cattle-guard for railway-tracks, consisting of the hollow cylinder C', having longitudinal flutes, coneaved on the outside and con- Vex on the inside, containing a resonant iilling, c, as and for the purpose described.

4. A cattle-guard for railway-tracks, consisting of the combination, with the revolving cylinders or rollers, of the intermediate plates, D, having cone-like projections a, with knobs or balls b, as and for the purpose described.
